Isabel is showing some blood in her urine. I called my vet and am bringing her in tomorrow AM for a urine test.

I have never found blood in one of my cats' urine before. She is only about 4 months old and I am really worried.

She told me something was wrong. I went in to scoop boxes tonight and she hopped in while I was scooping (she never has done that before) to pee...so I figured I'd wait and scoop that...and I noticed a drop of blood on top of the tiny (dime sized) pee spot. She went a few more times while I was in the cat room, always a small amount (like a peanut M&M) and I found another red-tinged spot.

I hope it is nothing serious. She doesn't seem to be in any pain and is playing right now.
